Modélisation des phénomènes de diffusion thermique dans un milieu fini homogène en vue de l’analyse, de la synthèse et de la validation de commandes robustes

Abstract : The work of this thesis concerns the study of the thermal diffusion phenomena to have a model (white box approach) for the analysis, the frequency synthesis and the time validation of robust commands. The Part 1 composed of chapter 1 focuses on the definitions and the interpretations of the integro-differential non-integer operator. The simulation problem in the time domain of the fractional differential systems is specified. Part 2 entitled "Analytical Study" includes two chapters whose objective is to make a detailed analysis of the fractional order behavior, first in a semi-infinite medium (chapter 2), then in a finite medium (chapter 3). Part 3, entitled "Numerical simulation of time responses" combining two chapters (4 and 5), aims the implementation of the "thermal process" plant (model validation of a finite medium) of a simulator of the thermal control loop time responses.
